QEDE Poll Mode Driver
======================
-The QEDE poll mode driver library (**librte_pmd_qede**) implements support
+The QEDE poll mode driver library (**librte_net_qede**) implements support
for **QLogic FastLinQ QL4xxxx 10G/25G/40G/50G/100G Intelligent Ethernet Adapters (IEA) and Converged Network Adapters (CNA)** family of adapters as well as SR-IOV virtual functions (VF). It is supported on
several standard Linux distros like RHEL, SLES, Ubuntu etc.
It is compile-tested under FreeBSD OS.
- VLAN offload - Filtering and stripping
- N-tuple filter and flow director (limited support)
- NPAR (NIC Partitioning)
-- SR-IOV VF
+- SR-IOV PF and VF
- GRE Tunneling offload
- GENEVE Tunneling offload
- VXLAN Tunneling offload
- MPLSoUDP Tx Tunneling offload
- Generic flow API
-Non-supported Features

Co-existence considerations
---------------------------
to the PFs of a given adapter and either qede PMD or Linux drivers
(qed and qede) can be bound to the VFs of the adapter.
+- For sharing an adapter between DPDK and Linux drivers, SRIOV needs
+ to be enabled. Bind all the PFs to Linux Drivers(qed/qede). Create
+ a VF on PFs where DPDK is desired and bind these VFs to qede_pmd.
+ Binding of PFs simultaneously to DPDK and Linux drivers on a given
+ adapter is not supported.

Supported QLogic Adapters
-------------------------
inbox in certain newer Linux distros under the standard directory
``E.g. /lib/firmware/qed/qed_init_values-8.40.33.0.bin``.
If the required firmware files are not available then download it from
- `linux-firmware git repository <http://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/qed>`_
- or `QLogic Driver Download Center <http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/DefaultNewSearch.aspx>`_.
- To download firmware file from QLogic website, select adapter category, model and DPDK Poll Mode Driver.
+ `linux-firmware git repository <http://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/qed>`_.
- Requires the NIC be updated minimally with **8.30.x.x** Management firmware(MFW) version supported for that NIC.
It is highly recommended that the NIC be updated with the latest available management firmware version to get latest feature set.

For downloading PF driver, select adapter category, model and Linux distro.

Performance note
~~~~~~~~~~~~~~~~
- For better performance, it is recommended to use 4K or higher RX/TX rings.
-Config File Options
-~~~~~~~~~~~~~~~~~~~
+Config Options
+~~~~~~~~~~~~~~
+
+The following option can be modified in the ``config/rte_config.h`` file.
-The following options can be modified in the ``.config`` file. Please note that
-enabling debugging options may affect system performance.
+- ``RTE_LIBRTE_QEDE_FW`` (default **""**)
-- ``CONFIG_RTE_LIBRTE_QEDE_PMD`` (default **y**)
+ Gives absolute path of firmware file.
+ ``Eg: "/lib/firmware/qed/qed_init_values-8.40.33.0.bin"``
+ Empty string indicates driver will pick up the firmware file
+ from the default location /lib/firmware/qed.
+ CAUTION this option is more for custom firmware, it is not
+ recommended for use under normal condition.
- Toggle compilation of QEDE PMD driver.
+The following options can be enabled with Meson flags.
-- ``CONFIG_RTE_LIBRTE_QEDE_DEBUG_TX`` (default **n**)
+- ``RTE_LIBRTE_QEDE_DEBUG_TX`` (default **disabled**)
Toggle display of transmit fast path run-time messages.
-- ``CONFIG_RTE_LIBRTE_QEDE_DEBUG_RX`` (default **n**)
+- ``RTE_LIBRTE_QEDE_DEBUG_RX`` (default **disabled**)
Toggle display of receive fast path run-time messages.

+When there are multiple adapters and/or large number of Rx/Tx queues

+descriptors may not be enough. Please increase the number of memzone
+descriptors to a higher number as needed. When sufficient number of
+memzone descriptors are not configured, user can potentially run into
+following error.

Driver compilation and testing
------------------------------
This section provides instructions to configure SR-IOV with Linux OS.
-**Note**: librte_pmd_qede will be used to bind to SR-IOV VF device and Linux native kernel driver (qede) will function as SR-IOV PF driver. Requires PF driver to be 8.20.x.x or higher.

#. Verify SR-IOV and ARI capability is enabled on the adapter using ``lspci``:
